Did you know?
WebMost central excitatory synapses possess both AMPA and NMDA receptors. Antagonist drugs that selectively block either AMPA or NMDA receptors are often used to identify synaptic responses mediated by each receptor type. WebAcetylcholine (ACh) is an important neurotransmitter that plays a role in brain functions, such as memory, and body functions, such as muscle contractions to move your muscles. Low levels of acetylcholine are associated with memory issues and muscle disorders. Cholinesterase inhibitors are used to treat Alzheimer’s disease and myasthenia gravis.
WebAn excitatory postsynaptic potential (EPSP) occurs if the membrane is depolarized by the ion movement. If, on the other hand, the membrane becomes hyperpolarized when the ions move, an inhibitory postsynaptic potential (IPSP) is generated. EPSPs and IPSPs are local potentials.
